File system

Hi alll

I am handling large no file. I would like to read all those file content and would like to extract some line from file. Is there any body help me out. I would like to get code or some logic that i write code myself.


Thanks
Ramesh

Hi RameshChaudhary :)

The principal is quite simple... you can read a whole file's contents like so:

PHP Code:

---

$fileContents = implode('', file('http://www.someplace.com/filename.xyz')); 


---

This will assign the contents of the file too the variable $fileContents.

Optionally though you could just do this:

PHP Code:

---

$fileContents = file('http://www.someplace.com/filename.xyz'); 


---

That would generate an array, each element of the array representing one line of the file - you could loop through those to find the required lines and use them.

Well each index in the array will correspond to the line number, such that:

PHP Code:

---

$fileContents = file('http://www.someplace.com/filename.xyz');  

// line 1
$line1 = $fileContents[0];

// line 2
$line2 = $fileContents[1];

Hi VisualAD,

--------------------------------------------------------------------------
$lines = file('C:/zipunzip/unzip/prifiles/0006509972022089.pri');

foreach ($lines as $line_num => $line) {
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";

}

$line1 = $lines[0];
$line2 = $lines[1];

Thanks

What on earth are you trying to do here?

Code:

---

$line1 = $lines[0];
$line2 = $lines[1];
$line3 = $lines[2];
$line4 = $lines[3];
$line5 = $lines[4];
$line6 = $lines[5];
$line7 = $lines[6];
$line8 = $lines[7];
$line9 = $lines[8];
$line10 = $lines[9];
$line11 = $lines[10];
$line12 = $lines[11];
$line13 = $lines[12];
$line14 = $lines[13];
$line15 = $lines[14];
$line16 = $lines[15];
$line17 = $lines[16];
$line18 = $lines[17];

:confused:

You need to use opendir() and readdir() to find all the files in a given directory.

z0mg. Don't copy them all to separate variables like that, it's pointless :)

If you want to view contents of all files in a folder you will have to loop through the files one by one and you can do that using scandir(). If you are using PHP 4 the alternative method of getting the filenames are also shown on the page a bit further down.

thanks

I would like loop contents of all files of directroy.

That's nice for you.

Take a look at the PHP manual for the functions that allow you to manipulate directories.

since you have your file read into an array $fileContents, simply loop through the array and check for your string.

ex.

PHP Code:

---

$search_string = "my string within quotes";
for($i=0;$i<=sizeof($fileContents);$i++){
//define your search term variable
$search_term = $fileContents[$i];

//check to see if this is your search string
if($search_term == $search_string){

 // do your stuff
}

}

i hope this helps

Thanks, modpluz

I have large number of files (*.j31) in directory. I would like to rename all files in 5099709047725.jpg. The file name comes after data processing. Want some logic to rename all files in a directory

thanks

You need to copy the file using copy() and then delete it using unlink().
